摘要：OBJECTIVE:To estimate the validity of three single questions used to assessself-reported hearing loss as compared to pure-tone audiometry in an adultpopulation.METHODS:A validity study was performed with a random sub-sample of188 subjects aged 30 to 65 years, drawn from the fourth wave of a population-based cohort study carried out in Salvador, Northeastern Brazil. Data werecollected in household visits using questionnaires. Three questions were usedto separately assess self-reported hearing loss: Q1, “Do you feel you have ahearing loss?”; Q2, “In general, would you say your hearing is ‘excellent,’‘very good,’ ‘good,’ ‘fair,’ ‘poor’?”; Q3, “Currently, do you think you can hear‘the same as before’, ‘less than before only in the right ear’, ‘less than beforeonly in the left ear’, ‘less than before in both ears’?”. Measures of accuracywere estimated through seven measures including Youden index. Responsesto each question were compared to the results of pure-tone audiometry toestimate accuracy measures.RESULTS:The estimated sensitivity and specificity were 79.6%, 77.4% forQ1; 66.9%, 85.1% for Q2; and 81.5%, 76.4% for Q3, respectively. The Youdenindex ranged from 51.9% (Q2) to 57.0% (Q1) and 57.9% (Q3).CONCLUSIONS:Each of all three questions provides responses accurateenough to support their use to assess self-reported hearing loss in epidemiologicalstudies with adult populations when pure-tone audiometry is not feasible.
